[gentoo-dev] linux-headers

[Alexander Holler]

Hello,

why are the linux-headers in /usr/include?

I would prefer to have the plain headers in /usr/src/linux-2.x.x-headers 
with a symlink from /usr/src/linux to that directory and just have symlinks 
from /usr/include/(asm|linux) to /usr/src/linux/include/(asm|linux).

In fact, now every compile uses the headers form the vanilla kernel, not 
from the actual installed kernel.

Kind regards,

Alexander Holler

The linux headers should only really be changed when you upgrade glibc, 
otherwise things get out of sync, perhaps we should upgrade the headers 
automatically in the glibc ebuild from the currently installed kernel.

Right, I think the linux-headers should be no normal package but get installed 
from the kernel includes that are present when you compile glibc. And perhaps 
a lil reminder somwhere. Many people don't know that it's supposed to be this 
way. (e.g. ppl coming from redhat only know about symlinks in that dir at 
least in 6 it was that way, dunno about 7)

Yes. I've used an old SuSE 7.3 with many packages compiled by myself and 
haven't had any problems up to now. And I'm sure, the glibc was very old 
(so I think it was compiled with a 2.2.x kernel) and last I've used kernel 
2.4.18 with the includes pointing at that kernel.

Why should the usr/include/linux and asm reflect the state at glibc compile 
time? Is there any reading about that?

Yes there is, google is your friend.

Use your preferred kernel mailinglist mirror or just view this one:

usr/include/linux should reflect the kernel version that your glibc was
compiled with, not the running kernel. if a program needs the running
kernel they should link to /lib/modules/`uname -r`/build/include/  and
the linux dir there, which should reflect the running kernel and is
setup by make modules_install.
